Title:
INDICATION SELECTION CIRCUIT FOR MULTIFUNCTIONAL WATCH
Document Type and Number:
Japanese Patent JPS5769284
Kind Code:
A
Abstract:

PURPOSE: To facilitate selection of only necessary functions from among attached functions conceived beforehand to indicate functions selected repeatedly by menans of a specified digit selection circuit, a memory circuit, a correction circuit and a gate circuit.

CONSTITUTION: A digit selection signal detection circuit 52 adapted to pick out only digit selection signals for necessary indication functions is provided at an output section of a digit selection ring counter 42 in an indication selecting circuit for sequentially repeated indication of functions of a multifunctional watch. A selector circuit 56 is provided with a memory circuit 58 to discriminate necessary attached functions from unnecessary ones by a digit selection signal 204 picked out with the digit selection signal detection circuit 52. In addition, a correction circuit 80 is provided to enable the selection of the subsequent functions nullifying unnecessary functions if selected by mistake checking the contents of the memory circuit 58 and a gate circuit 96 is provided to control indication of functions through the operation of a change-over circuit 56.
